由于在Ubuntu上没有对HD60 Pro的驱动程序支持，因此我想创建Windows 10 VM并通过捕获卡。

qemuqemu-kvmvirt-managerdmesg | grep 'IOMMU enabled'

这些是我的PCI设备...

但是，当我尝试添加设备时，启动VM时系统冻结了。我重新启动并尝试启动VM，但是系统再次冻结。

这也是可重复的：我可以创建一个新的VM并通过此YUAN设备，但是每当我尝试启动VM时它都会冻结。

如果我再次删除设备并启动VM，则会引发错误：

Error starting domain: internal error: Process exited prior to exec: libvirt:  error : unable to set AppArmor profile 'libvirt-318bbb3b-3e45-4ed9-9d77-7310bdb5d222' for '/usr/bin/qemu-system-x86_64': No such file or directory
